OK, in Aus I can see your point. Even here, some parts are depressingly hard to find.

While there are certainly many purists -- to each their own, it's your !@$!(! car! -- it's also a reaction to, at least here in the US, the 'stick a tree fitty innit' as if the chevy 350, a fine thing indeed, is the only 'other' engine choice.

There are AMC chassis that have problematic situations regarding engines -- i have one, a 'breadbox' American (63). The engine is very ancient, hard to find parts for, etc, and the engine compartment is very very small. With $$$$ you can do anything, and a 350 is just... boring and depressing.

You'd get less hassle and more appreciation, in my opinion of the car hobby art, if you chose a non-AMC engine that was particularly well suited for the task; eg. in the pre-64 Americans, a Ford 200, Nissan KA24, ... there's a guy around somewhere with a '58 or '59 beautifully fitting a Quad4. Now THAT is a pretty thing! Even if it wouldn't appease the "restore is the only option!" purists -- and I've met many -- from an enthusiast POV it gets solid nods. it's respectful of the car, appropriately sized (but with a supercharger!), etc.

It's your car and your business! This forum has a lot of diversity; lots of people just trying to eke out a few miles from old Betsy, to the AMX/Jav/SC V8 muscle car crowd, and a lot of stuff that doesn't fit any prefab category, like mine.

Hey,

Yeah i am not trying to get on anyones nerves, just questioning the idea but i can understand your logic.
Im in Newcastle Australia.... Thats my main problem, it is extreamly hard to find Rambler parts over here which is leaving me to look at other options..

Matt, i think i have seen a website or ur restoration work on the rambler in your avatar?

AMC offered the 290 in 1966 for a very short time but I'm not sure they offered it in the American. In 1967, they offered both the 290 and 343.  For 1968, you could only get the 290. For 1969, you could get a 290 or, if you ordered an SC/Rambler, the 390.

I think it was 66 that the 343 was offered for a short time. Few Americans left the factory with the 343 due to concerns about the chassis twisting on hard launches (it did!). The 69 SC/Rambler (390 V-8) had a stiffened chassis. The hardtop SC bodies had most of the convertible bracing installed (if not all) to combat twisting. Some could be installed in the older body. The converts had thicker inner rockers and thicker braces behind the rear seat. The rear seat brace was just doubled, I don't know for sure about the inner rockers, but they were most likely just double thickness as well. There may have been more things stiffened for the converts/SC, I'm not sure.

vinny -- you've never priced rebuilding a Jag 4.2L OHC six... let's not even talk about the V-12!! That's actually a very common swap (at least in the US) , with at least one company still making conversion kits (http://www.jagsthatrun.com/Pages/Jaguar_V-8.html). They have some Chevy V-8 swap parts that would come in handy for someone contemplating a late model EFI SBC engine swap.

I've seen one with a factory 343 and 4 speed manual T10. 

I looked at a Jaguar once. When the guy lifted the hood and I saw the sbc my interest was gone immediately.

Mickey, you're in Newcastle... Delaware (US)??

You can put any drivetrain in you want. It's your car. This is, however, an AMC forum dedicated to driving/restoring/preserving AMC vehicles, so AMC drivetrains, even when not original to that model car (say a late model in an early Rambler) is preferred. So you'll get a lot of negative reaction to installing a "foreign" drivetrain. You'll get some help from a few of us (like myself) who understand the reasons one may want to do that, but not from the majority. That's just the way it goes. Go to a Ford forum and tell them you'd like some help putting a Chevy 350 drivetrain in a Fairmont or Granada and you'll get the same results.

No, the SBC (small block Chevy) ISN'T a "popular" change for the Rambler. SBCs and other V-8s have been put in many other cars, including Ramblers. By far the most popular V-8 conversion is to a late model AMC V-8. Using other engines is getting to be more popular as AMC V-8s (and especially 2WD transmissions) are getting harder to find -- harder in some areas than others. If you do put a different make V-8 in go ahead and go with a modern fuel injected engine. At least that makes a little more sense because there is no such AMC animal. Yes, an AMC V-8 can be modernized in such a manner, but it would be costly using aftermarket parts. It could be done a bit cheaper using salvaged parts from other makes, but that's not for the novice. You can get a full SBC drivetrain from a wreck with the computer, wiring, and all for a reasonable price and go. Or a 5.0L Ford, or Chrysler, etc. It's about as much work to swap one as the other. The AMC drivetrain, by contrast, can literally bolt in as the late AMC V-8 was an option in those cars (the first of the late model AMC V-8s came out in late 1966 in the American, last one in 1991 in the Jeep Grand Wagoneer).

  No,  there's no mounting conversion brackets to ease putting a sbc in it.  Though Bulltear does make brackets to convert a 6 cyl crossmember to a AMC V8.

Ok cheers for the advice.

I've also had the thought of changing the whole engine and driveline to a 350 chev or something along those lines but im not sure how the conversion would go?

Are there some post on here regarding that, i've had a browse but found nothing that talks alot about a conversion...

I've also been told that i could probably buy some mounting conversion brackets to suit the chev as it was a popular change for the rambler..true??

For a street car go with part number 44242. That will net you a noticeable increase in low end power and get good gas mileage. AMC six cylinder cars are usually geared to cruise in the 2000-2500 rpm range (around 60-65 @ 2250 rpm). Over 3000 rpm will drop mileage (actually it's over 65-70 mph) considerably no matter what cam you have. It's overcoming wind resistance above 65-70 that's the problem. So gear and/or adjust tire size to cruise at about 70 @ 2400 rpm or so and you should have an economical cruiser. There are gear and tire size calculators at www.4lo.com (easy site to remember, there are others). See what difference just changing one tire series (like from a 70 down to a 65 series, same width) makes!

The 44243 wouldn't be bad, but the description does read for "spirited driving". Torque starts coming in @ 1500 rpm, which isn't too bad for a street motor, but you'll like the off-idle torque of the 44242 much better.

I do like the split duration of the Crower cams much better than the same duration for intake and exhaust. The AMC six seems to like the split duration a lot better. If I'd thought to look at Crower when I built my last six I would have seriously considered that 44242 for myself!
